It will be obvious if such tape recordings are produced and vetted.
If O'Reilly thought the woman could back up her claims, why didn't he pay her off instead of filing the extortion suit? Do you think that he was guilty, and just assumed she wouldn't have evidence?
I think that even if you're guilty, $60M is a lot of money-----especially if what you're accused of doesn't go beyond verbal indecency. O'Reilly seems like a proud guy. I can see how the thought of caving in to an extortionist harpie might be unpalatable to him.
